As shown in fig. 2 to 4, a bearing alignment preloading system according to an embodiment of the present invention includes:
the clamping head 300 is used for clamping the bearing with the reverse side facing downwards;
the clamping head 300 is connected with the rotary power device 400 and can horizontally rotate under the driving of the rotary power device 400;
the lifting power device 500 is connected with the rotating power device 400, and can drive the clamping head 300 to ascend to a first position and descend to a second position;
the lifting device comprises a fixed seat 600, wherein the fixed seat 600 is provided with a track 610 with an upper guide stroke and a lower guide stroke, and a lifting power device 500 is connected with the track 610;
the pre-pressing power device 700 is mounted on the fixing seat 600, the pre-pressing power device 700 is provided with an expansion rod 710 capable of extending up and down, and the expansion rod 710 is provided with an upper limiting block 720 and a lower limiting block 730 at intervals up and down;
the sliding connection block 740 is slidably sleeved on the telescopic rod 710, is positioned between the upper limiting block 720 and the lower limiting block 730, and is connected with the lifting power device 500;
Specifically, as shown in fig. 1 and 9, when the bearing aligning and pre-pressing system of the present invention is used, the clamping head 300 moves up and down under the action of the lifting power device 500 along with the rotating power device 400, and when the clamping head 300 is lifted to the first position, the bearing 200 is clamped by the clamping head 300, and the opposite side of the clamped bearing 200 faces downward.
Then the holding head 300 moves downwards to a second position under the action of the lifting power device 500, and the second position is determined by the position fixed by the gear 100 in the using process, namely when the holding head 300 moves to the second position, the lower surface of the bearing held by the holding head 300 is flush with the upper surface of the gear 100 arranged below.
Then, the extension rod 710 of the pre-pressing power device 700 extends downward, the upper limit block 720 moves downward, the pre-pressing spring 750 is pressed, the pre-pressing spring 750 applies a downward force to the sliding connection block 740, so that the sliding connection block 740 has a downward sliding tendency on the extension rod 710, and further, the lifting power device 500 has a downward movement tendency on the rail 610, but if the bearing 200 is misaligned with the gear 100 (i.e., the groove 210 and the positioning protrusion 111 are misaligned, and therefore, the positioning protrusion 111 blocks the bearing from being pressed into the shaft hole of the gear 100), the bearing cannot be further pressed into the shaft hole of the gear 100, and only after the bearing is aligned with the gear 100, the acting force of the pre-pressing spring 750 can be released, and the lifting power device 500 is driven to move upward and downward on the rail 610, so that the bearing is pre-pressed into the gear 100.
In order to align the bearing 200 with the gear 100 (i.e. the groove 210 and the positioning protrusion 111 are aligned), the rotary power device 400 rotates to drive the bearing 200 to rotate slowly, and during the rotation of the bearing, once the groove 210 and the positioning protrusion 111 are aligned, the resistance of the bearing 200 disappears, and under the action of the pre-pressing spring 750, the lifting power device 500 is driven to move up and down on the rail 610, so that the bearing 200 is pre-pressed into the gear 100, and the alignment pre-pressing of the gear 100 is completed (the pre-pressing spring 750 has a small extension, and can only complete a certain pre-pressing depth).
After the pre-pressing is completed, the rotation of the rotary power device 400 stops, the clamping head 300 loosens the bearing 200, the telescopic rod 710 of the pre-pressing power device 700 contracts upwards, the sliding connection block 740 moves upwards along with the lower limiting block 730, and the sliding connection block 740 drives the lifting power device 500 to return to the initial position. Then, under the action of the lifting power device 500, the clamping head 300 is driven to ascend to the first position, and a new bearing 200 is clamped again to perform the prepressing installation of the next round.
In some embodiments of the present invention, the lifting power device 500 is a lifting cylinder, the lifting cylinder is connected to the rail 610 through a mounting base 510, the lifting cylinder is provided with a lifting output shaft, and the rotating power device 400 is connected to the lifting output shaft.
Specifically, since the distance between the first position and the second position is determined, the lifting output shaft of the lifting cylinder only needs to set the stroke of the up-and-down movement to drive the rotary power device 400 to move up and down, and further drive the clamping head 300 to ascend to the first position and descend to the second position. In addition, the lifting cylinder is connected with the rail 610 through the mounting base 510, and the mounting base 510 slides up and down on the rail 610 to drive the lifting cylinder to move up and down. More specifically, the sliding connection block 740 is connected to the mounting block 510 to move the mounting block 510.
In some embodiments of the present invention, a position sensor 800 is disposed on the mounting seat 510 for checking a position height of the mounting seat 510.
Specifically, as shown in fig. 5, the position sensor 800 is disposed on the mounting seat 510, and when the sliding connection block 740 drives the mounting seat 510 downward, the position sensor 800 detects that the height of the mounting seat 510 is reduced in the process that the bearing 200 is pre-pressed into the gear 100, so as to determine that the bearing 200 is pre-pressed into the gear 100. In addition, if the position sensor 800 does not detect the change of the position height of the mounting seat 510 after the rotary power device 400 continues to rotate for a period of time, the device may be misaligned or the product may have quality problems, which may result in that the press-in is impossible (for example, the shaft hole of the gear has burrs, etc.), and the product is determined to be a defective product and is sent to a defective product area.
In some embodiments of the present invention, the lower limiting block 730 is movably connected to the telescopic rod 710, so that the height of the lower limiting block 730 can be adjusted. Specifically, the lower stopper 730 is a connection bolt, the connection bolt is connected to the lower end of the telescopic rod 710 through a screw, and the connection bolt can be separated from the telescopic rod 710, so that the pre-pressed spring 750 and the sliding connection block 740 can be conveniently mounted on the telescopic rod 710. Meanwhile, the distance between the upper limiting block 720 and the lower limiting block 730 can be adjusted by adjusting the connecting position of the connecting bolt, and the movement stroke of the sliding connecting block 740 on the telescopic rod 710 can be adjusted, so that the up-and-down movement stroke of the lifting power device 500 can be adjusted. In addition, the amount of expansion adjustment of the preload spring 750 may be adjusted to adjust the spring force of the preload spring 750.
